[CONNECT C++] App. version number

VersionNumber   	msVersion	{ 1, 2, 3, 4};
mdlSystem_setMdlAppVersionNumber (nullptr, &msVersion);

I put the above in MdlMain().  When I look at app. details in the MDL Applications dialog, the Version is blank.  I notice that most delivered applications also have a blank Version in that dialog.

How do we set the app. version no. in CONNECT?
